There have been three other accidents at the Hogback Bridge, all within 60 days.

Gray said, "A semi truck that was carrying a bunch of cars and trucks hit the bottom of the overpass and flew a truck and car onto the turnpike."

OHP officials, as well as the Oklahoma Turnpike Authority, said it is not the bridge, it's those who ignore height limits and travel illegally on the turnpike.

Jack Damrill, from the Turnpike Authority, says they are putting a fix in place.

He said, "We are starting a protection system for over height and overloaded trucks. So once that beam is hit, it will set off things that will notify people. One will be the highway patrol. And it will also have things set up around the road that will say, 'Please pull off into this section or into this area of the roadway."
